Application ilec November 5 of the disks is provided with shiftsble teeth representing the values to be transmitted to the registering mechanism, the desired number of the seid teeth being adopted 'to be shifted into operative positions by ineens of cern disks.

The object of the improvements is to Vprovide novel ineens for shifting the desired number of teeth into or out oi operetive positions.

,For the purpose oi' explaining the invention sha-ll refer to e -calculating machine which has been shown end described in detail in the United States Peten?, No 1,100,689; and i Wish it to he understood, that myv invention is not limited to the construction o the machine shown in the so companying drawing and that it ,may also be embodied in machines other than calenlziting machines.

loosely mounted on the shaft `y et one yside oi: each of the disks 'f and proiects either outward into operative positions or inward into inoperative positions. Nornisily the paivl is out of position for engagement with the. pins :1:1 and is held in this position by :i spring m. For placing the pewi in position for engagement with the pin e, com disk Z is provided and hes on e, portion of its circumference s coin fece Z1 the disk :Z being` rocked onlyyfor setting and resetting the teeth a?. As appears from Fie l, the Vopen port oi' the coin foce' l extends over the Vport oi' the circuinen ence of the L si; l which corresponds to the teeth Therefore the setting disk r und the te il ninehin craint; 1, without the teeth e; gagging tnpi. an, but when the d 'turned i. shown n 'T ,oavvl setting disk r. turned, ie 1 o2 con oe rotated by ineens of the l ircelj,7 rotated, so that the velue set thereon is transmitted to Vthe numeral wheel s.

in the embodiment shown in the drawing, the following mechanism is vrorided for turning the anni dish l. @n the machine freine a., shaft '7' is mounted which is provided at its left hand side with a hand lever j? for rotating the same (see Fig. 3), and the said shaft carries arms 1', one for each of the setting levers, the free ends of the said arms being connected with the cam disks Z through links h. By turning the shaft in the direction of the arrow jl shown in Fie. y1 the cam disks Z are also rotated, as is indicated in Fig. 1 by the position of the arm z' and the link t-shovn in dotted lines. The shaft j is common to all the cam disks Z, and the connection can either he such, that each of the links is connected with the shaft by' an arm i ot' its own, or such that all the links h are in engagement with a rod b which -is parallel to the shaft and rocks about the same, as is shown in Fig. 1.

Each of the setting levers t is locked in its-set positions by, means of a toothed sector t2 connected therewith and a spring actuated pawl f engaging in the teeth of theseetor. A

If after turning the cam disks Z and setting a value the machine crank were turned, before the cam disks Z are returned into their normal positions shown in Fig. l, the pins w1 of the teeth .fc would he engaged bythe pawls rov'ded ywith the cam slots, so that accoroing`to the direction of the rotation of the machine crank the teetht, which have been set in operative positions are retracted into inoperative positions or the teeth which are in inoperative positions are set in operative positions. To avoid this and to assure the proper operation of the machine, interlocking mechanism is provided hetiveeni the crank le and the shaft y' which turns the' cam disks, and which' interlocking mechanism is adapted to lock the crank as long as the cam disks have heen turned out ot' their normal positions. The interlocking mechanism is preferably constructed in such a n @inner as to lock cam disks Z', as longT as t .e crank is out of its normal position. Finally a third locking mechanism may be combined with the inter,- locking mechanism, by means of which the crank and the setting levers t aremade to he dependent on each other. To shoav what may be done, the drawing shows an example of such a construction.

Through the intermediary of gear wheels 751, 7a2, and 7c3 a locking disk g is connected with the machine crank k, and a lateral notch (/1 of the said locking disk is engaged hy a nose c1 'of a slide e. ln the normal position of the cam disks Z shown, in Fig. 2, the said slide is located opposite a notch Z1 of a disk .f7 secured to the driving shaft y' of the c'am disks. Zhen rotating the shaft y' for the purpose ot turningr the cam disks Z and in the direction of the arrow jl shown in Fig. l, the margin of the disk Z is shifted in 'front of the slide e so as to lock the same.

Thereby the marl. ie crank is also locked, for the reason that the slide e locks the disk g which is connected thereiviph. 'lfhereore, for releasing the crank the cam disks Z must always be rocked into initial positions. (in the other hand, when the ank is being retated, the disk f/ forces the slide e into notch of the disk LZ, sothat 'the shait j and the cam disks Z are locked to the end oi the rotation of the crank.

The slide e has the further function to interlock the setting levers t and the crank 1.1. For this purpose it is provided with notches c2 and opposite to the said notches arms f1 are located Which are connected with the locking pawls Zhen upon rotation of 'the machinecrank 7c the slide c is shifted hy means of' the disk g in the' direction of the arrow shown in Fig. 2, instead of the notches c2 the margin of the slide engages at the rear of the levers f1, so that the parvis and thereby the levers t are locked. Un the other hand, when either one o the levers t is not exactly in itsv setting position, the crank is locked, because in this case the corresponding pawl f which hears on a tooth of the sector t2 rocksI its arms f1 irzio the notclie2 of the slide e and thereby locks the slide and crank in the iiajperative positions.

rlhe slide'c is pulled a spring e into the inoperative position shown in Fig. For pressing the parvis f in contact with the sectors Z2 springs o are provided.
